Question

The temperature at midnight was 10 degrees. Over the next four hours, the temperature fell 20 degrees. What was the temperature at 4am?

Answer 1

-10 degrees

Step-by-step explanation

We have that the temperature at midnight was 10 degrees.

Midnight is 12 am (12:00 am)

Over the next four hours, the temperature fell 20 degrees.

Four hours after 12 am is 4 am.

Since the temperature fell, we can find the new temperature by subtracting 20 degrees from the initial temperature.

That is:

(10 - 20) degrees

= -10 degrees

That is the temperature at 4 am.
